Microstructure and electromagnetic characteristics of Ni nanoparticle film coated carbon microcoils

Carbon microcoils (CMCs) have been coated with a Ni nanoparticle film using an electroless plating process. The morphology, the elemental composition and the phases in the coating layer, complex permittivity and permeability of the CMCs and Ni-coated CMCs were, respectively, investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and microwave vector network analysis at room temperature. A homogeneous dispersion of Ni nanoparticles on the outer surface of the CMCs was obtained, with a mean particle size of ∼34.4 nm and the phosphorus content of about 8.5 wt%. When comparing the coated and uncoated CMC samples, the real (ε′) and imaginary (ε″) part of the complex permittivity as well as dielectric dissipation factor (tgδε = ε″/ε′) of the Ni-coated CMCs were much smaller, while the real (μ′) and imaginary (μ″) part of the complex permeability and the magnetic dissipation factor (t g σμ = μ″ / μ′) were larger. The enhanced microwave absorption of Ni-coated CMCs resulted from stronger dielectric and magnetic losses. In contrast, the microwave absorption of uncoated CMCs was mainly attributed to the dielectric rather than magnetic losses.

Representing places never visited: Landscape and the diasporic imagination

While landscape photography’s complicity with the colonial possession of new territory has been substantially discussed and well understood, this paper considers the role of the European landscape as the focus of diasporic desire. The interdisciplinary project, S2Q/Good Blood began as a social history map of Scandinavian and Nordic migration to Queensland in the nineteenth century, incorporating archival material from local collections with visual field trip data gathered in Denmark, Sweden, Norway and Finland. In 2011, some of this material found its way into the installation work, 'my mother is water, my father is wood'. What emerged from this experiment was an imaginary landscape, melding its loci through original photography and video footage in tandem with stock imagery and historical material. This juxtaposition reinforced the represented landscape as a narrative landscape and evidence of the performativity of belonging. This practitioner reflection utilizes Lynette Russell’s research into landscape archaeology to consider the significance of relationships with landscapes that are “not always empirically demonstrable.”

Claiming the moral high ground in the copyright wars

Copyright was once one of the more obscure areas of law. It applied primarily to resolve disputes between rival publishers, and there was a time, not too long ago, when ordinary people gave it no thought. Copyright disputes were like subatomic particles: everyone knew that they existed, but nobody had ever seen one. In the digital age, however, copyright has become a heated, passionate, bloody battleground. The 'copyright wars' now pitch readers against authors, pirates against publishers, and content owners against communications providers. Everyone has heard a movie producer decry the rampant infringement of streaming sites, or a music executive suggest that BitTorrent is the end of civilisation as we know it. But everyone infringes copyright on an almost constant basis - streaming amateur videos with a soundtrack that isn't quite licensed, filesharing mp3s, copying LOLcat pictures from Facebook, posting pictures on Pinterest without permission, and so on - and most know full well they're in breach of the law.

Climate-ready crops: Intellectual property, agriculture, and climate change

In The Climate Change Review, Ross Garnaut emphasised that ‘Climate change and climate change mitigation will bring about major structural change in the agriculture, forestry and other land use sectors’. He provides this overview of the effects of climate change on food demand and supply: ‘Domestic food production in many developing countries will be at immediate risk of reductions in agricultural productivity due to crop failure, livestock loss, severe weather events and new patterns of pests and diseases.’ He observes that ‘Changes to local climate and water availability will be key determinants of where agricultural production occurs and what is produced.’ Gert Würtenberger has commented that modern plant breeding is particularly concerned with addressing larger issues about nutrition, food security and climate change: ‘Modern plant breeding has an increasing importance with regard to the continuously growing demand for plants for nutritional and feeding purposes as well as with regard to renewal energy sources and the challenges caused by climate changes.’ Moreover, he notes that there is a wide array of scientific and technological means of breeding new plant varieties: ‘Apart from classical breeding, technologies have an important role in the development of plants that satisfy the various requirements that industrial and agricultural challenges expect to be fulfilled.’ He comments: ‘Plant variety rights, as well as patents which protect such results, are of increasingly high importance to the breeders and enterprises involved in plant development programmes.’ There has been larger interest in the intersections between sustainable agriculture, environmental protection and food security. The debate over agricultural intellectual property is a polarised one, particularly between plant breeders, agricultural biotechnology companies and a range of environmentalist groups. Susan Sell comments that there are complex intellectual property battles surrounding agriculture: 'Seeds are at the centre of a complex political dynamic between stakeholders. Access to seeds concerns the balance between private rights and public obligations, private ownership and the public domain, and commercial versus humanitarian objectives.' Part I of this chapter considers debates in respect of plant breeders’ rights, food security and climate change in relation to the UPOV Convention 1991. Part II explores efforts by agricultural biotechnology companies to patent climate-ready crops. Part III considers the report of the Special Rapporteur for Food, Olivier De Schutter. It looks at a variety of options to encourage access to plant varieties with climate adaptive or mitigating properties.

Divest Harvard: Climate justice, higher education, and fossil fuel divestment

On the 19 November 2014, seven Harvard students — the Harvard Climate Justice Coalition — have brought a legal action against Harvard University to compel it to withdraw its investments from fossil fuel companies. The plaintiffs include the Harvard Climate Justice Coalition; Alice Cherry, a law student; Benjamin Franta, a physics student interested in renewable energy; Sidni Frederick, a student of history and literature; Joseph Hamilton, a law student; Olivia Kivel, a biologist interested in sustainable farming; Talia Rothstein, a student of history and literature; and Kelsey Skaggs, a law student from Alaska interested in climate justice. The Harvard Climate Justice Coalition also bringing the lawsuit as ‘next friend of Plaintiffs Future Generations, individuals not yet born or too young to assert their rights but whose future health, safety, and welfare depends on current efforts to slow the pace of climate change.’ The case of Harvard Climate Justice Coalition v. President and Fellows of Harvard College, is being heard in the Suffolk County Superior Court of Massachusetts. The dispute will be an important precedent on the ongoing policy and legal battles in respect of climate change, education, and fossil fuel divestment.

Just label it: Consumer rights, GM food labelling, and international trade

In the United States, there has been fierce debate over state, federal and international efforts to engage in genetically modified food labelling (GM food labelling). A grassroots coalition of consumers, environmentalists, organic farmers, and the food movement has pushed for law reform in respect of GM food labelling. The Just Label It campaign has encouraged United States consumers to send comments to the United States Food and Drug Administration to label genetically modified foods. This Chapter explores the various justifications made in respect of genetically modified food labelling. There has been a considerable effort to portray the issue of GM food labelling as one of consumer rights as part of ‘the right to know’. There has been a significant battle amongst farmers over GM food labelling – with organic farmers and biotechnology companies, fighting for precedence. There has also been a significant discussion about the use of GM food labelling as a form of environmental legislation. The prescriptions in GM food labelling regulations may serve to promote eco-labelling, and deter greenwashing. There has been a significant debate over whether GM food labelling may serve to regulate corporations – particularly from the food, agriculture, and biotechnology industries. There are significant issues about the interaction between intellectual property laws – particularly in respect of trade mark law and consumer protection – and regulatory proposals focused upon biotechnology. There has been a lack of international harmonization in respect of GM food labelling. As such, there has been a major use of comparative arguments about regulator models in respect of food labelling. There has also been a discussion about international law, particularly with the emergence of sweeping regional trade proposals, such as the Trans-Pacific Partnership, and the Trans-Atlantic Trade and Investment Partnership. This Chapter considers the United States debates over genetically modified food labelling – at state, federal, and international levels. The battles often involved the use of citizen-initiated referenda. The policy conflicts have been policy-centric disputes – pitting organic farmers, consumers, and environmentalists against the food industry and biotechnology industry. Such battles have raised questions about consumer rights, public health, freedom of speech, and corporate rights. The disputes highlighted larger issues about lobbying, fund-raising, and political influence. The role of money in United States has been a prominent concern of Lawrence Lessig in his recent academic and policy work with the group, Rootstrikers. Part 1 considers the debate in California over Proposition 37. Part 2 explores other key state initiatives in respect of GM food labelling. Part 3 examines the Federal debate in the United States over GM food labelling. Part 4 explores whether regional trade agreements – such as the Trans-Pacific Partnership (TPP) and the Trans-Atlantic Trade and Investment Partnership (TTIP) – will impact upon

Lock the gate: Fracking, investor-state dispute settlement, and the Trans-Pacific Partnership

There has been much debate about the relationship between international trade, the environment, biodiversity protection, and climate change.The Obama Administration has pushed such issues into sharp relief, with its advocacy for sweeping international trade agreements, such as the Trans-Pacific Partnership and the Trans-Atlantic Trade and Investment Partnership. There has been much public concern about the impact of the mega-trade deals upon the protection of the environment. In particular, there has been a debate about whether the Trans-Pacific Partnership will promote dirty fracking. Will the Trans-Pacific Partnership transform the Pacific Rim into a Gasland?There has been a particular focus upon investor-state dispute settlement being used by unconventional mining companies. Investor-state dispute settlement is a mechanism which enables foreign investors to seek compensation from national governments at international arbitration tribunals. In her prescient 2009 book, The Expropriation of Environmental Governance, Kyla Tienhaara foresaw the rise of investor-state dispute resolution of environmental matters. She observed:'Over the last decade there has been an explosive increase of cases investment arbitration. This is significant in terms of not only the number of disputes that have arisen and the number of states that have been involved, but also the novel types of dispute that have emerged. Rather than solely involving straightforward incidences of nationalization or breach of contract, modern disputes often revolve around public policy measures and implicate sensitive issues such as access to drinking water, development on sacred indigenous sites and the protection of biodiversity.'In her study, Kyla Tienhaara observed that investment agreements, foreign investment contracts and investment arbitration had significant implications for the protection for the protection of the environment. She concluded that arbitrators have made it clear that they can, and will, award compensation to investors that claim to have been harmed by environmental regulation. She also found that some of the cases suggest that the mere threat of arbitration is sufficient to chill environmental policy development. Tienhaara was equally concerned by the possibility that a government may use the threat of arbitration as an excuse or cover for its failure to improve environmental regulation. In her view, it is evident that arbitrators have expropriated certain fundamental aspects of environmental governance from states. Tienhaara held: As a result, environmental regulation has become riskier, more expensive, and less democratic, especially in developing countries. This article provides a comparative analysis of the battles over fracking, investment, trade, and the environment in a number of key jurisdictions including the United States, Canada, Australia, and New Zealand. Part 1 focuses upon the United States. Part 2 examines the dispute between the Lone Pine Resources Inc. and the Government of Canada over a fracking moratorium in Quebec. Part 3 charts the rise of the Lock the Gate Alliance in Australia, and its demands for a moratorium in respect of coal seam gas and unconventional mining. Part 4 focuses upon parallel developments in New Zealand. This article concludes that Pacific Rim countries should withdraw from investor-state dispute settlement procedures, because of the threat posed to environmental regulation in respect of air, land, and water.

The culture wars of climate change

Of late, there has been a growth in cultural expression about climate change – with the rise of climate fiction (‘cli-fi’); art and photography responding to changes in nature; musical anthems about climate change; plays and dramas about climate change; and environmental documentaries, and climate cinema. Drawing comparisons to past controversies over cultural funding, this paper considers the cultural wars over climate change. This article considers a number of cultural fields. Margaret Atwood made an important creative and critical contribution to the debate over climate change. The work examines Ian McEwan's novel, Solar, a tragi-comedy about authorship, invention, intellectual property, and climate science. After writing a history of Merchants of Doubt, Naomi Oreskes and Erik Conway have experimented with fiction – as well as history. This article focuses upon artistic works about climate change. It analyses James Balog’s work with the Extreme Ice Survey, which involved photography of glaciers under retreat in a warming world. The work was turned into a documentary called Chasing Ice. It also considers the artistic project of 350.org 'to transform the human rights and environmental issues connected to climate change into powerful art that gets people to stop, think and act.' The paper examines musical storytelling in respect of climate change. The paper explores dramatic works about climate change including Steve Waters' The Contingency Plan, Stephen Emmott's Ten Billion, and Andrew Bovell's When the Rain Stops Falling and Hannie Rayson’s Extinction. The paper also examines the role of documentary film-making. It also considers the cinematographic film, Beasts of the Southern Wild. Such a survey will enable a consideration of the larger question of whether creative art about climate change matters; and whether it is deserving of public funding.

Harry Potter and the lexicon of doom

In a three day trial in April 2008, the United States District Court for the Southern District of New York considered whether the Harry Potter Lexicon infringed the intellectual property rights of J.K. Rowling and Warner Brothers. The case has attracted great media attention. As John Crace, a reporter for The Guardian, observed: “On one side: global-celebrity author J.K. Rowling. On the other: an amateur fan site devoted to the world's favourite boy wizard. At stake: the soul of Harry Potter.” J.K. Rowling is the author of the seven book Harry Potter series, which tell the story of a young wizard, Harry Potter, and his battles with Voldemort, the Lord of Darkness. As the court papers noted, “The Harry Potter Books are a modern day publishing phenomenon and success story.” Warner Brothers sought and obtained the film rights to the series. The entertainment company has thus far produced five films; a sixth is due in November 2008; and the final instalment is planned. The Harry Potter Lexicon is a reference guide created by Steven Vander Ark, a former grade school teacher. He has organised a large volume of material on the Harry Potter books and the Harry Potter films on a website in an alphabetical listing, from “A-Z”. The founder of RDR Books, Roger Rapoport, approached Ark to publish the Harry Potter Lexicon in a book form. Ark agreed to this request, and provided the publisher with a condensed version of the web-site. After RDR Books announced its intention to publish the reference book, J.K. Rowling and Warner Brothers brought a legal action in the United States District Court for the Southern District of New York, alleging that the publishers of the Harry Potter Lexicon were in breach of various intellectual property rights. A spokesperson for Warner Brothers and J.K. Rowling observed: "A fan’s affectionate enthusiasm should not obscure acts of plagiarism. The publishers knew what they were doing. The problem remains that the Lexicon takes an enormous amount of Ms. Rowling’s work and adds virtually no original commentary of its own. As we’ve said in court, it takes too much and adds too little. Authors have a duty to prevent the exploitation of their works by people who contribute nothing original, creative or interpretive." The litigation involves the intersection of copyright law, trade mark law, and consumer protection law. It has a wider significance because it deals with the protection of authorial rights; the use of literary indexes, supplements and reference guides; and the clash between character merchandising and fan fiction.

Single layer lead iodide: Computational exploration of structural, electronic and optical properties, strain induced band modulation and the role of spin-orbital-coupling

Graphitic like layered materials exhibit intriguing electronic structures and thus the search for new types of two-dimensional (2D) monolayer materials is of great interest for developing novel nano-devices. By using density functional theory (DFT) method, here we for the first time investigate the structure, stability, electronic and optical properties of monolayer lead iodide (PbI2). The stability of PbI2 monolayer is first confirmed by phonon dispersion calculation. Compared to the calculation using generalized gradient approximation, screened hybrid functional and spin–orbit coupling effects can not only predicts an accurate bandgap (2.63 eV), but also the correct position of valence and conduction band edges. The biaxial strain can tune its bandgap size in a wide range from 1 eV to 3 eV, which can be understood by the strain induced uniformly change of electric field between Pb and I atomic layer. The calculated imaginary part of the dielectric function of 2D graphene/PbI2 van der Waals type hetero-structure shows significant red shift of absorption edge compared to that of a pure monolayer PbI2. Our findings highlight a new interesting 2D material with potential applications in nanoelectronics and optoelectronics.

Sports anti-siphoning laws and the controversy of sports broadcasting: A case study of Pakistan

Controversies between private and public broadcasters over the broadcasting of live sports, especially cricket, during important sports events have emerged as a serious legal issue in Pakistan. Controversy between Geo Super and Pakistan Television over live telecast of the ICC Cricket World Cup is a typical example of such controversies. An aggressive legal battle, during a most important cricketing event, not only hampered the enjoyment of cricket viewers across the country but also gave Pakistan a bad name across the globe. This article discusses in detail this controversy and highlights lacunas in the existing sports broadcasting regime of Pakistan. There are no clear and well defined sports broadcasting laws in Pakistan. The Pakistan Electronic Media Regulatory Authority (PEMRA) rules are of general nature. Secondly, PEMRA rules are not comprehensive and explicit enough to provide clear guidelines about sports broadcasting. This may be a possible reason why sports broadcasting controversies reach the highest court in Pakistan, the Supreme Court of Pakistan. Despite these ugly battles between broadcasters, the government of Pakistan has never given due importance to this issue and no efforts have been made at any level to come up with legislation on sports broadcasting to avoid such controversies or to resolve them amicably in the light of well-defined laws on this subject. The purpose of this article is to draw the attention of the concerned authorities towards this important issue because in future more such controversies may be expected in the absence of a sports broadcasting regime in the country.

Predicting the last brand standing in the supermarket price wars

On January 26, 2011, grocery retailer Coles fired the first salvo in what would soon be dubbed the “supermarket price wars” by reducing the price of its own-brand milk to A$1 per litre. Woolworths immediately responded. In the three years since, grocery prices have been tumbling, with 85 cent bread being the latest “sacrificial lamb”. This period of intense competition has brought about not just lower grocery prices, but a senate enquiry, and increasing media and analyst interest.

Australian feature films and distribution: Industry or cottage industry?

Feature films remain critical flagships to any national film industry. Australian feature films can be highly commercial endeavours that also perform symbolic functions by embodying the national imaginary in big screen based sound and imagery. They conduct a dialogue with domestic audiences as well as showcase key aspects of Australia in the global film festival circuit. As the pre-eminent filmmaking form, feature films also serve as important launchpads for the careers of many Australian writers, directors, actors and technical crew. In the wake of over a decade of diminished share of local box office obtained by Australian feature films, Australian Feature Films and Distribution: Industry or cottage industry, examines issues in the production sector affecting the performance of Australian feature films and some responses by the central funding and support screen agency, Screen Australia.

Reconstituting identity and history in post-war Mostar, Bosnia-Herzegovina

This paper by Carl Grodach demonstrates the careful unravelling of complexity, diversity, contestation and contradictions involved in the reconstruction of symbolic urban spaces after violent conflict, and the allied processes of cultural reinterpretation, political reconfiguration and material revaluation which accompany it. The paper analyses the reconstruction and redevelopment of the 16th-century historic centre of Mostar, Bosnia-Herzegovina, following the Bosnian Wars of 1992–1995. Reconstruction efforts centre around Stari Most, the 16th-century Ottoman bridge destroyed by Bosnian Croat military in 1993. In Mostar, both international and local organizations are in the process of reinterpreting Bosnia’s legacy of Ottoman city spaces. This research and analysis illuminates how such spaces can be central to contemporary projects to redefine group identities and conceptions of place. It provides insight into the ways various groups are attempting to reshape outside perceptions of the city—and Bosnia’s ethnic conflict—to articulate a new definition of local identity and ethnic relations and to remake a stable tourist economy through Mostar’s urban spaces.

Waters Wars [Dramaturg]

'Water Wars' is one of three new performance works that were a component of Kathryn Kelly's PhD by Performance at the University of Queensland: 'Pedagogy of Dramaturgy: A Practice Framework to train Dramaturgs." Kathryn Kelly was engaged as a dramaturg on each performance work, and each is the basis of case study material used in the training program developed as part of the PhD.
